The instructions use commands that rely on the use of the unauthenticated git:// protocol, and do not work when changing the url to https:// or gits://

Can the repo be updated to use https:// correctly when pulling dependencies?

Calling the fetch script with 'http' instead of 'git' worked:

fetch clone http

Also in the fetch script, upstream=git:// needs to be replaced with upstream=https://
